US Patent 8057083 Fibre bundle confocal endomicroscope

A fiber bundle confocal microscope or endoscope (200), comprising a light source (142) for providing a beam of light (160), a coherent fiber bundle of optical fibers (152), a scanner (202) for receiving the beam and scanning the beam over a proximal end of the bundle (162), so that the beam is launched into a plurality of the fibers sequentially, a plurality of the fibers thereby acting sequentially as an at least one delivery fiber (204), a spatial filter (172), and a photodetector (174) operatively associated with the spatial filter to receive return light from one or more of the fibers. The return light from the delivery fiber is excluded from the photodetector by the spatial filter.
